Comparative Study of 27-Gauge Versus 25-Gauge Vitrectomy With Air Tamponade in the Treatment of Myopic Foveoschisis

Ophthalmic Surg Lasers Imaging Retina. 2018 Oct 1;49(10):e135-e142. doi: 10.3928/23258160-20181002-16.

Abstract

Background and objective: To compare the surgical outcome of 27-gauge pars plana vitrectomy (PPV) with 25-gauge PPV and evaluate the efficacy of air tamponade for the treatment of myopic foveoschisis (MF).

Patients and methods: Sixty eyes of 60 consecutive patients were recruited to undergo vitrectomy, internal limiting membrane (ILM) peeling, and air tamponade for treatment of MF. These eyes were divided into two groups: the 27-gauge group (n = 29) and the 25-gauge group (n = 31).

Results: There were no significant differences in the mean operating time (P = .32), the mean time for vitrectomy (P = .20), and the suturing rate(P = .46) between the 27-gauge group and the 25-gauge group. At the final follow-up, anatomical resolution rate did not differ between the two groups (P = .65).

Conclusion: The 27-gauge vitrectomy system is as efficient and feasible as the 25-gauge system for the treatment of MF. Air tamponade can provide good postoperative anatomic resolution of MF. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e135-e142.].
